title: Approaching the limit: can one DNA strand assemble into defined nanostructures?
abstract: This article reports a simple, symmetrical DNA building block (motif): a bulged DNA duplex consisting of two short, identical strands. Multiple copies of the same motif can interact with each other through T junctions. The resulting superstructures include predesigned 1D and 2D arrays that have been visualized by atomic force microscopy (AFM).
